About ICC profiles
One of the methods Photoshop can use to manage
color is based on the use of ICC profiles. An ICC
profile is a color space description. The ICC profile
format was defined by the International Color
Consortium (ICC) as a cross-application
standard. ICC profiles help you reproduce colors
accurately across different platforms, devices,
and ICC-compliant applications (such as Adobe
Illustrator and Adobe PageMaker
Adobe Photoshop uses a Color Management
Module (CMM) to interpret the ICC profiles that
describe the RGB and CMYK color spaces you are
using in your system. You can select from existing
ICC profiles or create your own. These profiles can
then become part of your image files. The CMM
interprets the ICC profiles to automatically
manage color issues among different color models
as well as color issues between your monitor, other
monitors, and the final print image. Although you
do not have to use ICC profiles, it can greatly
simplify managing color.
Important: To ensure that color management works
correctly on your system, change the color
management settings every time you change
printing devices.
